[SOLVED] Wireless USB adapter

I just bought a gigabyte aircruiser N300 usb adapter to increase the wireless signal.

But i cant get to work. I tried disabling the onboard wireless card. and used the command hwdetect --show -net, and checked what was new after i plugged in the adapter. it was only rt2800usb. I added that to the module and rebooted, but i still dont see any wlan when i type sudo ifconfig.

What am i doing wrong?

Re: [SOLVED] Wireless USB adapter

From what I see, this card uses Ralink RT2860 chipset. And the best way to get it work is by installing the windows driver using nspluginwrapper.

Re: [SOLVED] Wireless USB adapter

Thanks for your response.

I followed the guide. but i used ndiswrapper and ndiswrapper-utils instead. cause nspluginwrapper is for x64 systems.

this is the results:

sudo ndiswrapper -i /media/GIGABYTE/n300/drivers/gn-wb30n_wb31n/winxp2k/rt2870.inf
installing rt2870 ...
ndiswrapper -l
sudo modprobe ndiswrapper
rt2870 : driver installed
device (1044:800C) present (alternate driver: rt2800usb)

but i still only have one wlan present when i type sudo ifconfig. and thats the onboard.

should i put rt2800usb in the module blacklist or something?

Re: [SOLVED] Wireless USB adapter

I used the rt2870 driver cause the exact model number for the adapter is GN-WB31N-RH and drivers/gn-wb30n_wb31n/ was the closest i could find.

and how do i uninstall drivers? cause now i have both rt2860 and rt2870 installed. and none of them work.

Re: [SOLVED] Wireless USB adapter

You should use rt2800usb - in-kernel drivers are always preferable to other solutions such as ndiswrapper. Make sure the linux-firmware package is installed, and check dmesg and your logs for clues about it failing to work.

Re: [SOLVED] Wireless USB adapter

Here's a page on the wiki
https://wiki.archlinux.org/index.php/Rt … _and_on.29

and you might want to try backlisting rt2800usb rt2x00usb and rt2x00lib modules.
Also post the outputs of lsusb and dmesg | tail just after plugging the card in.

Re: [SOLVED] Wireless USB adapter

Okey, i get mixed answers here.

I got it to work yesterday. after i did sudo yaourt -S rt2870. but then i disconnected it to check if it really was the usb adapter. and i t was. but after a reboot its gone again.

which logs can i check? i can see the usb adapter with lsusb. but dmesg have ALOT of output and i dont know what to look for.

edit:my newbie guess is that the onboard wlan card and usb adapter is in conflict. and is it possible to have 2 wlan cards active?

edit2: this USB adapter is using RT2870 . is that in the kernel? and why should i use rt2800usb then?RT2870

Re: [SOLVED] Wireless USB adapter

Ok. i get it to work after installing rt2870 from AUR and putting rt2870sta in modules. but i cant access any sites. i had a similar problem on another laptop, but it was fixed by putting rt2800lib & rt2800pci in module blacklist. but when i do on this laptop the adapter doesnt work. maybe i should blacklist something else?

Re: [SOLVED] Wireless USB adapter

ok. i thought that the adpater would appear automaticly as  ra0 after a reboot. but all i had to do was to "sudo iwconfig" and there it was, as wlan1. then it was ready to go. with rt2800usb driver.

thanks again for the help.
